摘要: The present disclosure provides methods for purifying products from a fluid. In some embodiments, provided purification methods use a combination of purification modes (e.g., protein A and ion exchange) operated in tandem, wherein at least one of the modes utilizes weak partitioning. In some embodiments, provided purification methods operate under robust conditions in which a degree of binding between a product and resin is maintained despite variations in operating parameters.

摘要: This invention relates to methods of using weak partitioning chromatography for the purification of a product from a load fluid containing one or more impurities. Further, the invention relates to methods of weak partitioning chromatography defined by operating conditions which cause a medium to bind least 1 mg of product per mL of medium, or alternatively, defined by a partition coefficient of at least 0.1.
